BLOWER AND EXHAUSTER FOR AIR AND OTHER GASES.

SPECIFICATION forming part of Letters Patent No. 431,571, dated July 8, 1890.

Application filed March 23, 1889.

To all whom it may concern:

Be it known that I, CHARLES FIEssE, a citizen of the Republic of France, residing at 205 Grand street, New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Blowers and Exhausters for Air and other Gases; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in the improved form of blower and eXhauster for air and other gases,hereinafter to be described and claimed.

In the drawings, Figure 1 is a side view of my apparatus. Fig. 2 is a vertical longitudinal section of Fig. 1. Fig. 3 is a detail view of the preferred form of nozzle employed.

In the drawings like reference letters refer to like parts throughout.

The object of my invention is to compress, and thereby drive forward, a current of air or, gases, and also to exhaust the same from any closed chamber, and to purify or otherwise act upon the said gases by forcing them through the openings IV.

A and B represent any suitable standards, upon which my apparatus rests.

G is a hollow cylinder, which has at one end the conical nozzle D and at the other end a suitable head G, which has openings J.

. cylinder F is a helical thread L.

In my preferred form of apparatus, as illustrated, the cylinder F terminates at either end in cones E and E. Upon the rear cone E are mounted a suitable number of triangular blades V, inclined to the left. From the small end of the conical nozzle D a suitable outlet-pipe 0 extends, and is opened by a valve 0'.

Outside of the conical nozzle D is placed a second casing O, which is also preferably of a conical form. This casing forms a second and external chamber, which has an outlet Q, controlled by avalve Q. The cylinder G,

the conical nozzle D, and the external casing O are held together by bolts X, passing through Serial No. 304,488. (No model.)

their flanges. The shaft II is caused to revolve by a belt running over the pulley K, or

by any other suitable form of gearing.

Certain portions of the conical nozzle D are cut away, as shown at W in Fig. 3, and the openings thus formed are covered by any suitable material which will serve as a strainer for removing impurities from the air orgases and otherwise acting upon the-same. Said openings W may also be closed by any suitable cover or material impervious to gases when desired. 4

R is a hopper, into which pulverized fuel may be fed, if desired, and S is any suitable stirrer, mounted in the bearings S and S and revolved by the pulley Z.

In operation my invention may be used simply as an air and gas blower or exhauster; or it may be used to compress and forward the air, and at the same time to separate from it impurities or otherwise act upon it. In the first case the valve Q will be closed and the opening to the hopper R plugged up, or the openings W closed by suitable covers, as before. Then when the shaft H is caused to revolve the triangular blades V will draw in the air or gas from the open air or from suitable pipes connected with the openings J, and the helical thread L will drive the said air or gas forward through the conical nozzle D and out through the passage-way O and open valve 0 into any suitable pipe or receptacle. .In

the second case the valve Q will be opened full and the valve 0' closed. Then the action of the compressor will force the air through the sieves or screens stretched across the openings W, and the gases, which in consequence flows out into the chamber formed by the surrounding casing O and from there through the passage-way Q and valve Q, will be cleansed and more or less affected by the action of the screens stretched across the openings WV, as above described.

As illustrated in Fig. 2, pulverized fuel may be fed down from a hopper R and borne into any suitable furnace upon the current of air passing through the passage-way Q.

' Of course the current of air or gases may be heated or cooled in any one of the number of well-known ways.

Vhen the openings "W are closed, as before described, the air which is drawn in by the ICO ' end of said casing, a conical nozzle attached to the other end of said casing, a cylinder of lesser diameter, which terminates at either end in a cone revolving Within said cylindrical casing, a screw-thread mounted on said revolving cylinder, and curved blades mounted upon the rear conical end of said cylinder and revolving before the above-mentioned openings, substantially as described.

2. In an air and gas blower and exhauster, the combination of a cylindrical casing, suitable openings for the admission of air at one end of said casing, a conical nozzle attached to the other end of said casing, a cylinder of lesser diameter, Which terminates at either end in a cone revolving Within said cylindrical casing, a screw-thread mounted on said revolving cylinder, and curved blades mounted uponthe rear conical end of said cylinder and revolving before the above-mentioned openings, together with a second conical nozzle of larger diameter surrounding and inclosing the first nozzle, openings in and through the sides of said first nozzle, and separate valves cont-rolling the outflow from each of said nozzles, substantially as described.

In testimony whereof I affix my signature in presence of tivo witnesses.
